It’s creamy, garlicky, cheesy, and oh-so-satisfying—without knocking you out of ketosis. Plus, it’s easy enough to make on a Tuesday but elegant enough for a Friday date night. Let’s cook this together, step by step. You ready?

Why This Recipe Works

Before we roll up our sleeves, let me break down why this recipe just works. The shrimp are juicy and tender, the sauce is rich and cheesy, and the garlic… well, garlic makes everything better, right? And since this dish skips the heavy carbs, you won’t miss the bread or potatoes.

The Ingredients (Keep It Simple)

Here’s what you’ll need:

  • 1 lb raw shrimp (peeled and deveined)
    Look for medium or large shrimp—they hold up better in the oven.
  • 4 garlic cloves, minced
    Fresh garlic, not the jarred stuff. It makes a difference, trust me.
  • 1 cup heavy cream
    This is the base of your sauce. Keto-friendly and rich.
  • 1/2 cup grated Parmesan cheese
    Go for freshly grated if you can. The pre-shredded stuff doesn’t melt as nicely.
  • 1/2 cup shredded mozzarella cheese
    Melty, gooey perfection on top.
  • 2 tbsp butter
    Butter makes everything better.
  • 1 tbsp olive oil
    Adds a nice flavor to the shrimp.
  • 1 tsp paprika
    A little color and a hint of smoky flavor.
  • 1/2 tsp red pepper flakes (optional)
    If you like a little heat.
  • Salt and black pepper to taste
  • Fresh parsley, chopped
    For a sprinkle of green at the end.

Let’s Cook!

Step 1: Prep the Shrimp

Start by patting your shrimp dry with a paper towel. This little step ensures they don’t steam in the oven—they’ll get a nice caramelized edge instead. Toss the shrimp in a bowl with olive oil, paprika, salt, and black pepper. If you’re feeling adventurous, add a dash of red pepper flakes.

Step 2: Sauté the Garlic

Heat up a skillet over medium heat. Melt the butter, then toss in the minced garlic. Stir it around until your kitchen smells like heaven (about 1-2 minutes). Don’t let the garlic brown—it’ll get bitter, and we’re not about bitter tonight.

Step 3: Make the Sauce

Pour the heavy cream right into the skillet with the garlic. Stir it gently, scraping up any little garlic bits stuck to the pan. Let it simmer for 3-4 minutes until it thickens slightly. Then, whisk in the Parmesan cheese. The sauce should get creamy and velvety—like something you’d order in a fancy restaurant.

Step 4: Assemble the Dish

Grab an oven-safe dish or small casserole pan. Spread the shrimp out in a single layer. Pour the garlic cream sauce over the top, making sure every shrimp is coated. Sprinkle the mozzarella cheese evenly over everything.

Step 5: Broil Until Golden

Set your oven to broil (high heat!) and pop the dish in for 5-7 minutes. Keep a close eye on it—you want the cheese bubbly and golden, not burnt. The shrimp will cook quickly, so don’t wander off to check your phone.

Step 6: Garnish and Serve

Take your masterpiece out of the oven and sprinkle it with fresh parsley. That little pop of green makes it look as good as it tastes. Serve it hot, straight from the pan, and enjoy the oohs and ahhs from whoever’s lucky enough to share this meal with you.

What to Serve with Your Gratin

This dish is a whole meal on its own, but if you want to round it out, here are some ideas:

  • Zucchini noodles or spaghetti squash: A great low-carb option to soak up the sauce.
  • Steamed or roasted veggies: Broccoli, asparagus, or cauliflower pair beautifully.
  • Side salad: A simple green salad with olive oil and lemon dressing keeps things fresh.

Tips for Success

  • Choose the Right Shrimp
    Fresh or frozen shrimp both work, but make sure they’re deveined and cleaned. If you use frozen, thaw them fully and pat them dry to avoid excess water in the dish.
  • Don’t Overcook
    Shrimp are sneaky—they go from perfectly cooked to rubbery in a blink. That’s why we broil them for just a few minutes.
  • Adjust the Heat
    Love a little spice? Add extra red pepper flakes. Can’t handle the heat? Skip it entirely. This dish is flexible.
  • Use Fresh Parmesan
    Pre-grated cheese often has additives that prevent it from melting smoothly. Freshly grated Parmesan gives you that creamy, silky sauce you’re dreaming of.
  • Make It Your Own
    Want to add some extra flavor? A squeeze of lemon juice before serving brightens everything up. Or mix in some sautéed mushrooms for a hearty twist.

One More Thing…

This Keto Garlic Shrimp Gratin isn’t just dinner—it’s a little bit of luxury in the middle of your busy life. Cooking doesn’t have to be complicated to be amazing. When you scoop that first bite onto your plate and see the cheese stretch, you’ll know it was worth every second in the kitchen. So, light a candle, pour yourself a sparkling water (or wine, if that’s your style), and savor this delicious creation.

Whether you’re cooking for yourself or sharing it with someone special, I hope this recipe feels like a warm hug from my kitchen to yours. Let me know how yours turns out—I’d love to hear about it!

Frequently Asked Questions (FAQs)

Can I use pre-cooked shrimp?

You can, but they won’t absorb the sauce as well, and they might overcook under the broiler. If you must use pre-cooked, add them to the dish just before broiling and reduce the cook time.

Is this dish freezer-friendly?

Not really. The creamy sauce doesn’t freeze well—it tends to separate when reheated. Stick to making it fresh; it’s worth it.

Can I substitute the heavy cream?

Coconut cream could work if you’re dairy-free, but the flavor will be slightly different.
